E2
Multicooker displays E2 and will not start or aborts cooking shortly after heating begins.
Bottom Temperature Sensor (NTC) Short Circuit
E3
Display shows E3 during cooking, often when using high-heat functions like sauté or steam; cooker stops heating.
Overtemperature Protection – Bottom Sensor High Reading
E4
Display shows E4 and cooking cannot start or is interrupted; often associated with high-heat or pressure-style programs on certain Aroma multicookers.
Overtemperature Protection – Lid / Upper Sensor High Reading
E5
Multicooker displays E5 and refuses to start or stops mid-cycle, often on keep-warm or low-heat programs.
Bottom Temperature Sensor Out of Range / Calibration Error
E6
Display shows E6 and the cooker will not heat; error appears immediately on power-up or when starting a program.
Lid / Upper Temperature Sensor Open or Short Circuit
E7
E7 appears on the display and the cooker will not start; sometimes occurs after a power surge or lightning event.
Internal Control Board Fault / Sensor Circuit Failure
E8
E8 error appears and the cooker will not heat or shuts down quickly after starting.
Heater Drive Circuit Fault / Relay or Triac Failure
E9
E9 is displayed and the cooker will not start any program; sometimes accompanied by unresponsive or flickering display.
Power Supply / Low Voltage Error
Err
Display shows "Err" or "Error" without a number; cooker beeps and will not start or cancels the program.
General Control Error / Invalid State
H2O
Display shows a water-related warning (e.g., "H2O" or "Add Water") and the cooker will not start or stops heating.
Dry Pot / Low Water Protection
LID
Display shows a lid-related message (e.g., "LID" or flashing lid icon) and the cooker will not start; some Aroma models beep continuously until lid is closed correctly.
Lid Closed Sensor / Microswitch Not Engaged
Symptom
Buttons on the control panel do not respond or only some buttons work intermittently.
Keypad / Control Panel Failure
Symptom
Cooker starts but shuts off prematurely; rice or food is undercooked and the unit switches to Keep Warm too early.
Premature Boil-Over Detection / Incorrect Temperature Sensing
Symptom
Display and buttons work, but the countdown timer does not advance; cooker appears stuck at the initial time.
Control Logic / Timer Processing Fault
Symptom
Display is dim, flickering, or segments are missing, but the cooker still heats.
Display Module or Backlight Failure
Symptom
Exterior of the cooker becomes excessively hot to the touch during normal cooking.
Insulation or Thermal Shielding Degradation
Symptom
High-pitched squealing, buzzing, or humming noise from the cooker during operation.
Vibration or Electrical Noise from Heater or Transformer
Symptom
Inner pot coating is peeling, flaking, or heavily scratched; food sticks badly and may show dark flakes.
Nonstick Coating Degradation
Symptom
Inner pot rocks or wobbles on the heating plate; uneven cooking or clicking noises occur.
Deformed Inner Pot or Heating Plate
Symptom
Keep Warm function does not maintain temperature; food cools down too quickly or stays too hot and dries out.
Keep-Warm Temperature Control Fault
Symptom
Lid does not stay open and falls closed unexpectedly when lifted.
Lid Hinge / Spring Mechanism Wear
Symptom
Lid will not close or latch properly; cooker cannot start because the lid sensor is not engaged.
Lid Latch Misalignment or Damage
Symptom
Loud clicking, popping, or metallic noises from the base during heating or cooling.
Thermal Expansion Noise / Loose Internal Components
Symptom
Multicooker does not power on at all; no lights or display when plugged in.
No Power / Dead Unit
Symptom
Multicooker trips the household circuit breaker or GFCI outlet when starting a cooking program.
Heater or Wiring Short to Ground
Symptom
Rice or food is consistently overcooked, scorched at the bottom, or burns even when following Aroma recipes.
Overheating / Temperature Regulation Drift
Symptom
Slow Cook or Soup functions never reach a simmer; food remains undercooked even after extended time.
Low-Temperature Heating Underperformance
Symptom
Steam and starchy water leak from around the lid during cooking; liquid drips down the sides of the cooker.
Lid Seal / Gasket Failure or Vent Blockage
Symptom
Steam vent cap rattles excessively or pops off during cooking.
Steam Vent Cap Fitment Issue
Symptom
Strong burning smell or visible smoke from the cooker during operation.
Overheating or Electrical Short
Symptom
Unit beeps repeatedly and cancels cooking when moved or bumped slightly during operation.
Intermittent Sensor or Power Connection
Symptom
Unit powers on but will not heat; programs count down but food remains uncooked and the heating plate stays cool.
Open Heating Element Circuit
Symptom
Unusual plastic or chemical odor from the cooker during use, persisting after several cooking cycles.
Overheating Plastic Components or Residual Manufacturing Oils
Symptom
Water or condensation collects excessively under the cooker or on the countertop during use.
Condensation Management / Collector Overflow
